Students at two Williamson County schools were sent home early Monday after a strong gas odor forced the evacuation of the buildings.
The principals at Page Middle School and Page High School notified authorities of the smell around 8 a.m.
The schools were evacuated and students were bused to the Ag Expo Park on Long Lane.
Parents were alerted of the evacuation through a series of automated phone calls.
No one was injured.
In a late morning briefing, school officials said they would be dismissing students from the Ag Park at 1:30 p.m., after the students were fed lunch.
Parents were also able to pick up their children.
Shuttles took the students who drove to Page High School back to the school to pick up their vehicles.
A spokesperson for Atoms Energy said officials believe the strong odor was the result of the heat being turned on for the first time.
The gas odor was stronger than it would normally be because the lines have remained idle all summer.
Late Monday afternoon school officials said classes would resume on Tuesday.
Page Middle and High has a combined enrollment of about 1,700 students.
